HPLC assay method validation of tablet | Repetability Section
REPEATABILITY:
Aim:
To determine the degree of agreement among individual test results when the procedure is applied repeatedly to multiple samplings of a homogenous sample.
Method:
1. Using test method, prepare 6 sample solutions and record the accurate sample weights.
2. The assay according to a method, injecting each sample solution in duplicate.
3. Calculate the content of each sample as % and determine the mean and % RSD.
Acceptance Criteria:
The % RSD of the standard content of replicate (Six) samples must not exceed 2%.
Results:
